Room and zone management via IP network

The RAC18-IP controller is a multifunctional device that ensures the appropriate comfort in a single room or zone of the building. With the built-in 18 outputs and inputs, the Ethernet and serial ports and the use of additional expansion cards, the controller can be used versatilely in terms of lighting and shutter control, integration and monitoring.

At the cutting edge of technology

High-performance, IoT-enabled nano Edge Engine-based devices provide unprecedented new opportunities. Save valuable time with automatic BACnet data point export, real-time programming and take advantage of cloud connectivity.

Openness and reliability

Take advantage of IP connectivity with open protocols such as MQTT, BACnet, Modbus and ensure the highest building energy efficiency with any monitoring system. The controllers are equipped with a unique "fail-safe" solution on each Ethernet port for maximum reliability.

Seamless programming and maintenance
You can maintain and program your device from anywhere, in real time, with a free tool developed for this purpose. Thanks to the replaceable SD card, system and user data can be moved easily.
